At the end of the communication cable there is a Subcon under water contact, 4-pole, with locking sleeves. The communication cable is used twisted with the Interspiro DP1 hose, approximately 5-6 twists/metre of hose.
If the IBSOPHONE is used without the hose, there is a life line available with a breaking strength of 2000 kg.
